ABSTRACT

The general arrangement, principle of operation, and basic technical characteristics of pyroelectric noncontact local-temperature meter with nonmechanical (electronic) modulation of infrared radiation operating in the range 300-800°C are described. The device is intended for measuring the temperature of solid bodies inside vacuum assemblies. The meter can be used in the systems used to control and adjusting various technological processes (laser and electric welding, plasma and zonal melting) and also for diagnosing the temperature of the almost in accessible objects (furnaces, engines, high-voltage equipment, etc.).
